Changing color of a Bitmap via AS

Howdy,

i have a question and hopefully someone can help me out.

I have a white Bitmap (looks like a triangel with sum logo inside), now i want to change the whole color of the Bitmap to Black, like you can do with a Motiontween but in Actionscript. Is that possible and if yes, how can i manage this?

thanx for ya help and time

cheers
